Potentially the worst article I've seen on HN. It spends several paragraphs stereotyping women, damning them for caring about looks, and then promoting the author's superiority for basically being smarter than them. (He understands the social hierarchy thing, they don't.) Then, without irony, he appeals to Natalie Portman, who is someone that is - wait for it - attractive.
Girls like guys who look nice for the same reason guys like girls who look nice: it's more attractive.
It doesn't matter if it's stereotypical, only if it's accurate. I would like to hear an argument against the accuracy, and would love if citations were included.
It's another set of rules to play with, another system to hack. Learn the game and have some fun, that's what I did.
When I say something is stereotypical, I imply its inaccurate by being too general. Some women will do this, some won't. More importantly, some people will do this, and some won't. All people are involved in social hierarchies, and make judgments based on them. You're participating in one right now.
